Randomized Controlled Trial Comparative Study
Local anesthetic effects of Lidocaine cream: randomized controlled trial using a standardized prick pain.
ELA-max (4% lidocaine) and EMLA cream (lidocaine-prilocaine 2.5%) are topicals used for superficial anesthesia. Only few studies have been published on their comparative effectiveness in close-to-practice pain models. ⋯ This study confirms that a topical preparation with 4% lidocaine is an effective and safe treatment option for superficial anesthesia. It supports the claim that an occlusive application is more rapid in action. 4% lidocaine is of value as a rapidly-acting local anesthetic for the treatment of minor surgical procedures.

Mohs surgery allows excision of skin cancer in a tissue-sparing fashion that minimizes recurrence risk. While the indications for Mohs surgery are well established, factors predictive of complex Mohs cases are less studied. ⋯ Mohs cases are similar in complexity whether in academic or private practice. Recurrent/aggressive histology tumors, tumors >1 cm, and tumors on the nose or ear are more likely to prove surgically complex. Advanced knowledge of these factors may be useful pre-operatively as Mohs surgeons plan their scheduled cases.
